Adolescents With Breakthrough COVID-19 Infections Requiring Hospitalization: A Multicenter Retrospective Study.

Background Vaccines have the most important role in the battle against the COVID-19 pandemic. With the widespread use of vaccines, COVID-19 has remarkably declined. Adolescents were vaccinated after approvals for this age group, which was later than adults, and a nationwide vaccination program was implemented in August 2021 in Turkey for adolescents ≥12 years of age. Therefore, we aimed to determine the effects of the COVID-19 nationwide adolescent vaccination program on adolescent hospitalizations due to COVID-19 and multisystem inflammatory syndrome in children (MIS-C) by comparing two periods, including the vaccination period (VP) and the pre-VP (PVP). The second aim of this study is to compare the clinical features and disease severity of vaccine-breakthrough COVID-19 hospitalizations with unvaccinated individuals in the VP. Methods A retrospective multicenter study was conducted to determine and compare the number of hospitalizations due to COVID-19 and MIS-C between the VP (September 1, 2021, to August 31, 2022) and PVP (September 1, 2020, to August 31, 2021). We also compared the characteristics, risk factors, and outcomes of breakthrough infections of adolescents aged 12-18, which required hospitalization with the same age group of unvaccinated hospitalized individuals during the VP. Results During the study period, 3967 children (0-18 years) were hospitalized in the PVP and 5143 (0-18 years) in the VP. Of them, 35.4% were adolescents (12-18 years) in the PVP, and this rate was 18.6% in the VP; relative risk was 0.6467 (95% confidence interval [CI]: 0.6058-0.6904; p < 0.001). Patients with breakthrough COVID-19 were older (201 vs. 175 months, p < 0.001) and less commonly hospitalized for COVID-19 (81.5% vs. 60.4%, p < 0.001, odds ratio [OR]: 0.347 [95% CI: 0.184-0.654]). The majority of these infections were asymptomatic and mild (32% vs.72.9%: p < 0.001, OR: 5.718 [95% CI: 2.920-11.200]), and PICU admission was less frequently required (p = 0.011, OR: 0.188 [95% CI: 0.045-0.793]). Most breakthrough COVID-19 infections occurred within three months after the last vaccine dose (54.2%). Conclusions This study demonstrated a significant decrease in adolescent hospitalizations due to COVID-19 and MIS-C after implementing COVID-19 vaccines in Turkey. Breakthrough cases were less severe and mostly occurred three months after the last dose. This study emphasizes the importance of COVID-19 vaccines and that parents' decisions may be changed, particularly those who hesitate to or refuse vaccination.

Congenital Rubella syndrome: A short report and literature review.

Rubella infections are rarely seen where immunization programmes are in place. Congenital rubella syndrome is however still observed where the vaccination programme against rubella is not administered or interrupted. We present such a case, with typical clinical anomalies including congenital cataracts, sensorineural hearing loss and bone lesions. The diagnosis was verified by detection of rubella immunoglobulin M positivity in the mother in the first trimester and positive rubella serology in both baby and mother.

Detection of Deregulated miRNAs in Childhood Epileptic Encephalopathies.

The term "epileptic encephalopathy" is used to describe a possible relationship between epilepsy and developmental delay. The pathogenesis of developmental encephalopathies, independent of epilepsy, can be defined by genetic control mechanisms. The aim of this study was to investigate the use of miRNAs as serum biomarkers for the determination and discrimination of epileptic encephalopathies. Whole blood samples obtained from 54 individuals in 2 groups designated as epileptic encephalopathy patients' group (n = 24) and healthy controls (n = 30) were included in this study. The expression levels of 10 miRNAs were determined using qRT-PCR. After the determination of expression levels, the correlation of upregulated miRNA levels and Ki67 index was calculated using Pearson correlation test. The comparison of epileptic encephalopathy patients' group with healthy controls revealed the upregulation of one miRNAs (hsa-miR-324-5p) and downregulation of three miRNAs (hsa-miR-146a-5p, hsa-miR-138-5p, hsa-miR-187-3p). It has been determined that miRNAs with altered expression are an important factor in the formation of epileptic seizures and seizure-induced neuronal death. The fact that processes that play a key role in epiloptogenesis are under the control of miRNAs causes miRNAs to become meta-controllers of gene expression in the brain. We thought that further studies are needed to prove that especially hsa-miR-146a-5p, hsa-miR-138-5p, and hsa-miR-187-3p can be used as epileptic encephalopathy biomarkers. The detection of disease-specific miRNAs could contribute to the development of precision treatments.

Croup as a Previously Unrecognized Symptom of COVID-19 in Infants.

Although the most common symptoms of coronavirus disease 2019 (COVID-19) in children are fever and cough, cases of croup associated with COVID-19 are reported in the literature and have increased sharply with the Omicron variant. We present severe acute respiratory syndrome coronavirus 2 as a viral agent in an infant presenting with croup.

Transcobalamin II deficiency in twins with a novel variant in the TCN2 gene: case report and review of literature.

Objectives Transcobalamin II (TC) is an essential plasma protein for the absorption, transportation, and cellular uptake of cobalamin. TC deficiency presents in the first year of life with failure to thrive, hypotonia, lethargy, diarrhea, pallor, mucosal ulceration, anemia, pancytopenia, and agammaglobulinemia. Herein, we present TC deficiency diagnosed in two cases (twin siblings) with a novel variant in the TCN2 gene. Case presentation 4-month-old twins were admitted with fever, respiratory distress, vomiting, diarrhea, and failure to thrive. Physical examination findings revealed developmental delay and hypotonia with no head control, and laboratory findings were severe anemia, neutropenia, and hypogammaglobulinemia. Despite normal vitamin B12 and folate levels, homocysteine and urine methylmalonic acid levels were elevated in both patients. Bone marrow examinations revealed hypocellular bone marrow in both cases. The patients had novel pathogenic homozygous c.241C>T (p.Gln81Ter) variant in the TCN2 gene. In both cases, with intramuscular hydroxycobalamin therapy, laboratory parameters improved, and a successful clinical response was achieved. Conclusions In infants with pancytopenia, growth retardation, gastrointestinal manifestations, and immunodeficiency, the inborn error of cobalamin metabolism should be kept in mind. Early diagnosis and treatment are crucial for better clinical outcomes. What is new? In literature, to date, less than 50 cases with TC deficiency were identified. In this report, we presented twins with TCN2 gene mutation. Both patients emphasized that early and aggressive treatment is crucial for achieving optimal outcomes. In this report, we identified a novel variation in TCN2 gene.

Retrospective evaluation of childhood paraphenylenediamine intoxication due to black henna.

BACKGROUND AND OBJECTIVES: Paraphenylenediamine (PPD) is a toxic substance in henna. Oral intake of this substance causes severe systemic toxicity. To the best of our knowledge there are no studies in the literature conducted only on children exposed to henna intoxication. METHODS: Twenty-three patients aged between 1 and 17 who referred to Nyala-Sudan Turkey Training and Research Hospital between May 2015 and June 2018 were evaluated retrospectively in terms of demographic, clinic and laboratory characteristics. RESULTS: Four (17.39%) patients were male and 19 (82.61%) were female. Average age of patients was 10.95 ± 3.2. Most of the referrals to the hospital following PPD intoxication occurred in the first 16 hours. All of the patients between 10 and 17 had taken henna for suicidal purposes. All patients had vomiting and agitation. The most common symptoms apart from these were gastrointestinal symptoms, tachycardia, tachypnea and dyspnea. Twelve (52.17%) patients had elevated liver function tests and 3 (13.04%) had developed renal failure. None of the patients had neurological complications. Two (8.70%) patients developed a need for tracheostomy. Average hospitalization period of patients was 8.5 days. Two patients died. One was in 1-5 age group and died due to renal complications, while the other was in 6-10 age group and died due to hepatic failure. CONCLUSION: PPD intoxication is a life-threatening situation even in low doses. For this reason, even asymptomatic cases should undergo physical examination and should be followed closely in terms of respiratory tract obstruction. Ensuring hydration and diuresis in the early period, steroid and adrenalin therapy for prophylaxis in terms of respiratory tract obstruction are important and tracheostomy should not be abstained in necessary cases. It should not be forgotten that symptomatic treatment for organ systems and dialysis will decrease mortality and morbidity.

The association between seizure self-efficacy of children with epilepsy and the perceived stigma.

This study used a descriptive, correlational, and cross-sectional research design to evaluate the effect of seizure self-efficacy of children with epilepsy on their perceived stigma of seizure. The study was conducted with 303 children with epilepsy. The data of the study were collected using "the Seizure Self-Efficacy Scale for Children" and "the Scale for Perceived Stigma in Children with Epilepsy". The mean age of the children included in the study was 12.65 ±â€¯2.37. The correlation between seizure self-efficacy of the children and their perceived seizure stigma was examined; a strong, significant, and negative correlation was found. It is recommended that the awareness of all health professionals should be increased in approaching children with epilepsy and that self-efficacy and stigma should be addressed.

Congenital Total Eversion of Upper Eyelids in a Normal Newborn.

Here, the authors report a rare case of congenital bilateral upper eyelid eversion with severe chemosis that was successfully managed by nonsurgical ways. A 2-hour-old male newborn with bilateral congenital upper eyelid eversion and severe chemosis was properly treated with conservative management consisting of the application of the antibiotic, steroid, and artificial tear drops and ointments in combination with padding the exposed conjunctiva with normal saline-soaked gauzes. The management was resulted in prompt and satisfactory resolution on the 14th day. Congenital upper eyelid eversion being typically a rare clinical entity is reported more frequently in African population. Although this unfavorable condition could end up with destructive complications like loss of vision, a reasonable anatomical outcome with good cosmetic results can be effectively achieved by conventional methods. Therefore, a thorough ocular examination should be carried out to exclude other ocular or systemic complications.
